Hmmm maybe your sway bar
Hi! I just installed my 6" RC suspension lift and there was a metal on metal rubbing sound, I took the wheels back off and the dust covers were rubbing, so I thought that was it. The noise is not that offen now, but is still there, and only happens at certain speeds and I tap the brakes and it goes away for awhile. I have not yet got a wheel alignment, could this sound have something to do with the brakes, camber or alignment???
